I want to display image based on another templatefield value.

Example person num(0010200) and image saved in folder is 00102000.jpg , if person num(01234) and image saved in folder is 01234.jpg, etc. like this i have many employee images.and this all saved in /img/ webfolder.

Now when ever lable2 person num changes i need to change the image1 which will be same as person num,

please suggest me to achieve the same. example code below.

<asp:TemplateField HeaderText="person_num" SortExpression="person_num">
<asp:BoundField DataField="full_name" HeaderText="full_name" SortExpression="full_name" />
<asp:TemplateField HeaderText="Image">

First of all, I consider you want to have a small change in the scenario you have presented in the question i.e,

Quote:
Example person num(0010200) and image saved in folder is 00102000.jpg , if person num(01234) and image saved in folder is 01234.jpg

It should be either
-- person_num = 0010200 then image = 0010200.jpg (note: 2 zeros at the end instead of 3 as stated in the question considering it to be a typo)
person_num = 01234 then image = 01234.jpg
-- person_num=0010200 then image = 00102000.jpg (note: 1 more zero added at the end, same as question)
person_num = 01234 then image = 012340.jpg (1 more zero added to at the end)

For the first case if you are saving the images as the same name as person_num you can use following code without any other logic added to it.

HTML

<itemtemplate headertext="Image">
     <img src="<%# Eval("person_num","~/Images/{0}.jpg") %>" <br="" mode="hold"> </itemtemplate>

For the second case, you need just very simple change i.e,
